Application filed May 7,1913. Serial No. 766,112.

T 0 all whom it may concern Be it known that T, ROBERT DELAUNAY-BELLEVlLLE, citiz'enof the French Republic,

residing at St Denis, Department of "the Seine, in Franceyhave inventedcertain new and useful Improvements in Valves, and I do'hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertai'ns to make and use the same. v

This invention relates to temperature regulators, and has for its objectto provide such a device having the novel features of construction andoperation hereinafter set forth.

The specific form of the temperature regulator herein disclosed wasdeslgned for use in combinatio/n with the generator of a Specification.of Letters Patent.

torpedo, but as will hereinafter appear, it

may be used in other relations where it is desired to control thetemperature of a fiuid by automatically varying the supply of fuel tothe fluid heating means, in accordance with the changes in temperatureof the fluid.

The invention consists in providing a tube containing a vaporizableliquid, which tube is subjected to the heat of the fluid whosetemperature is to be controlled. This tube is connected to a Bourdontube, the free end of which moves in accordance with the internalpressure and is connected by means of levers with a member whichcontrols the admission of fuel to the fluid heating means, a springbeing provided to balance the thrust exerted by the fuelon the end ofthe control member. A rigid and direct trans mission device, free fromplay or lost motion is employed between the free end of the Bourdon tubeand the control member, this transmission device comprising anoscillating lever to which the free endof the Bourdon tube is attachedand to which is also connected a slide valve, such that the output ofthe fuel is regulated in proportion to the travel of the free end .ofthe Bourdon 'tube. The valve is .so constructed that the passage of thefuel therethrough will vary in direct proportion to the movement of thevalve, and this feature, in combination with the features ofconstruction above stated, produce a temperature regulator capable ofmaintaining the temperature of any fluid constant at all times.

en used in combination with the gen- VALVE.

Patented positioned as to be subjected to the. heat of.

the gases in the torpedo generator, and the valve is employed to controlthe supply of fluid fuel to the generator. It is, therefore, obviousthat the valve will be actuated-t0 admit more or less fuel to thegenerator in accordance with the temperature of the gases of thegenerator.

The accompanying drawing shows by way of example an embodiment oftheinvention.

The fluid, such as the gases of the generator of a torpedo, thetemperature of which it is desired to maintain at a constant value,circulates within the wall 1 and immersed therein is a coiled tube 2filled with a liquid the vapor tension of which as a function of thetemperature is known. This coiled tube (which could be alsofreplacefd bya straight tube) communicates through the conduit 3 with the bent pipe 4similar to those used in dial manometers. It is known that the free endof this tube moves owing to the internal pressure which expands it. Thecurve of this movement is a function of the internal pressure and may beeasily experimentally determined. It is possible therefore to know thelawof the movement of the point 5 on the curve'6 which is substantiallya straight line, as a function of the temperature of the fluid in 1. Theliquid fuel, on reaching 7, passes into the chamber, 8 and traverses theport 9 to reach the combustion chamber through the conduit 10.

As the drawing illustrates, a movable spindle 11 can more or less closethe port 9. For this purpose, the spindle 11 is connected to the point 5which is the free end of the tube 4. The lever 13 oscillates about astationary point 14. It is possible to amplify at will, the extent ofthedisplacem'ent of the point 5 and therefore to obtain, an extremelysensitive regulation.

'In thecase of a sudden rise in'temperature within the chamber 1, thevapor tension in the tube 3 will also rise and the Bourdon tube willstiffen, the point 5 will reach, for example 5', the-lever 13 will beoscillated and the point 15 will move to 15' and the spindle 11 willmoveto 11' thus closing the fuel passage. In order that the Bourdon tube maynot be affected by the pressure which the fuel exerts on the end of thespindle, this; thrust: is equilibrated by a spindle.

instead of acting on the fuel admission,

the regulator may operate so as to regulate by means of a flap orthrottle valve or the like the quantity of Water injected into agenerator of the kind above referred to.

' I claim:

Apparatus of the kind described comprising valve actuating means, alever pivoted intermediate its ends to said means, said lever beingpivoted at one end to a stationary part of the construction, valvemechanism adapted to regulate the passage of fluid therethrough indirect proportion to its 20 movement, and comprising a slide valve and avalve seat provided with a rectangular opening, and a direct connectionbetween said valve and the free end of said lever.

In testimony whereof I aflix my signature, 25
